  英語, 研究論文（学術雑誌）, Abstract. Basal sliding in the ablation zone of the Greenland Ice Sheet is
  closely associated with water from surface melt introduced to the bed in
  summer, yet melting of basal ice also generates subglacial water year-round.
  Assessments of basal melt rely on modeling with results strongly dependent
  upon assumptions with poor observational constraints. Here we use surface and
  borehole measurements to investigate the generation and fate of basal
  meltwater in the ablation zone of Isunnguata Sermia basin, western
  Greenland. The observational data are used to constrain estimates of the
  heat and water balances, providing insights into subglacial hydrology during
  the winter months when surface melt is minimal or nonexistent. Despite
  relatively slow ice flow speeds during winter, the basal meltwater
  generation from sliding friction remains manyfold greater than that due to
  geothermal heat flux. A steady acceleration of ice flow over the winter
  period at our borehole sites can cause the rate of basal water generation to
  increase by up to 20 %. Borehole measurements show high but steady basal
  water pressure rather than monotonically increasing pressure. Ice and
  groundwater sinks for water do not likely have sufficient capacity to
  accommodate the meltwater generated in winter. Analysis of basal cavity
  dynamics suggests that cavity opening associated with flow acceleration
  likely accommodates only a portion of the basal meltwater, implying that a
  residual is routed to the terminus through a poorly connected drainage
  system. A forcing from cavity expansion at high pressure may explain
  observations of winter acceleration in western Greenland.

  The Greenland ice sheet and peripheral ice caps are rapidly losing mass. This mass change hasbeen captured by satellite remote sensing, but more detailed investigations are necessary tounderstand the spatiotemporal variations and mechanism of the ice loss. It has increased particularlyin northwestern Greenland, but in-situ data for northern Greenland are generally sparse. To betterunderstand the ice mass loss in northwestern Greenland, we studied the ice sheet, ice caps and calvingglaciers in the Qaanaaq region, as a part of the Green Network of Excellence (GRENE) Arctic ClimateChange Research Project. Field and satellite observations were performed to measure the mass lossof the ice caps and calving glaciers in the region. Detailed processes were investigated based on fieldmeasurements to understand mechanisms driving the ice loss. The field activities include massbalance monitoring on Qaanaaq Ice Cap since 2012, integrated field observations near the front ofBowdoin Glacier since 2013 and ocean measurements near the calving glaciers. In this contribution,we summarize the results of the GRENE Greenland project, and introduce an overview of the nextproject to be carried out under the framework of the Arctic Challenge for Sustainability Project(ArCS)., 低温科学第75巻編集委員会, 英語, 速報，短報，研究ノート等（大学，研究機関紀要）
